Conversion formula

The conversion factor from liters to deciliters is 10, which means that 1 liter is equal to 10 deciliters:

1 L = 10 dL

To convert 2.1 liters into deciliters we have to multiply 2.1 by the conversion factor in order to get the volume amount from liters to deciliters. We can also form a simple proportion to calculate the result:

1 L → 10 dL

2.1 L → V_(dL)

Solve the above proportion to obtain the volume V in deciliters:

V_(dL) = 2.1 L × 10 dL

V_(dL) = 21 dL

The final result is:

2.1 L → 21 dL

We conclude that 2.1 liters is equivalent to 21 deciliters:

2.1 liters = 21 deciliters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 deciliter is equal to 0.047619047619048 × 2.1 liters.

Another way is saying that 2.1 liters is equal to 1 ÷ 0.047619047619048 deciliters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that two point one liters is approximately twenty-one deciliters:

2.1 L ≅ 21 dL

An alternative is also that one deciliter is approximately zero point zero four eight times two point one liters.
